How to read XML document and display the output as string in c#
提问by Patan
consider my source file looks like this.
考虑我的源文件看起来像这样。
<Content xmlns="uuid:4522eb85-0a47-45f9-8e2b-1x82c78xx920">

I want to write a code, which read this xml document from a location and display it as string.
我想编写一个代码，它从一个位置读取这个 xml 文档并将其显示为字符串。
say name of the xml file is helloworld.xml.
Location: D:\abcd\cdef\all\helloworld.xml.
I have tried the following, but i was unable to do it.
我已经尝试了以下，但我无法做到。
XmlDocument contentxml = new XmlDocument();
contentxml.LoadXml(@"D:\abcd\cdef\all\helloworld.xml");
Response.Write("<BR>" + contentxml.ToString());
Response.write is displaying nothing. Correct me if i missed any thing. Its not creating any component and error is coming.
Response.write 没有显示任何内容。如果我错过了什么，请纠正我。它没有创建任何组件，错误即将到来。
I have also tried this,
我也试过这个，
XmlDocument contentxml = new XmlDocument();
try
{
contentxml.LoadXml(@"D:\abcd\cdef\all\helloworld.xml");
}
catch (XmlException exp)
{
Console.WriteLine(exp.Message);
}
StringWriter sw = new StringWriter();
XmlTextWriter xw = new XmlTextWriter(sw);
contentxml.WriteTo(xw);
Response.Write("<BR>" + sw.ToString());
But i did not find the any output.
但我没有找到任何输出。

You need the OuterXmlproperty:
你需要的OuterXml财产：
Response.Write("<BR>" + contentxml.OuterXml);
Also you are loading a filenot xml so use
此外，您正在加载一个不是 xml的文件，因此请使用
contentxml.Load(@"D:\abcd\cdef\all\helloworld.xml");
instead of
代替
contentxml.LoadXml(@"D:\abcd\cdef\all\helloworld.xml");

If you want to simply write a file to the output, you can do Response.WriteFile.
如果您只想将文件写入输出，则可以执行Response.WriteFile。

try this
尝试这个
XmlTextReader reader = new XmlTextReader (@"D:\abcd\cdef\all\helloworld.xml");
while (reader.Read())
{
Console.WriteLine(reader.Name);
}
Console.ReadLine();

Do you really have to deserialize the XML at all? Why not just read it as a text file? Something like..
你真的需要反序列化 XML 吗？为什么不将其作为文本文件读取？就像是..
String text = File.ReadAllText(@"D:\abcd\cdef\all\helloworld.xml");
Response.Write(text);
With appropriate error handling obviously..
显然有适当的错误处理..

I would try using the XDocumentclass:
我会尝试使用XDocument该类：
//load the document from file
var doc = XDocument.Load("..."); //== path to the file
//write the xml to the screen
Response.Write(doc.ToString());
If you want to use an XmlDocumentinstead, you would want to use Loadinstead LoadXml.
如果你想用 anXmlDocument代替，你会想用Loadinstead LoadXml。

String text = File.ReadAllText(Server.MapPath("~/App_Data/sample.xml"));
txtData.Text = text;
